1SDA058119R1 ABB E6V-A 5000 PR122/P-LSI 5000 A 3-Pole Air Circuit Breaker

Why Choose the ABB E6V-A 5000 PR122/P-LSI Air Circuit Breaker?

The ABB E6V-A 5000 PR122/P-LSI, order code 1SDA058119R1, is a high-performance SACE Emax air circuit breaker (ACB) designed for switching and protection of high-current low-voltage electrical distribution systems. This three-pole breaker combines a 5000 A rated current with ABB's advanced PR122/P-LSI R5000 electronic overcurrent release for dependable protection in demanding industrial, commercial and infrastructure installations.

Part of the ABB SACE Emax E6V-A series, this model is supplied in a fixed three-pole configuration with horizontal rear terminals. The PR122/P-LSI release provides long-time, short-time and instantaneous protection functions, helping protect conductors, busbars and distribution equipment against overload and short-circuit conditions.

The E6V-A 5000 is engineered for power systems with very high prospective fault currents. This V-performance version provides a 125 kA short-circuit current rating at 480 V together with a 100 kA short-time withstand current, making it suitable for high-capacity switchboards where strong fault interruption performance and selective protection are required.

Reliable Protection for High-Capacity Power Distribution

Air circuit breakers such as the ABB E6V-A provide switching and electronic overcurrent protection for major low-voltage distribution circuits. The PR122/P-LSI release monitors circuit current and provides long-time protection against sustained overloads together with short-time and instantaneous functions for rapid protection against short-circuit conditions.

With its 5000 A rating, 125 kA short-circuit capability at 480 V and 100 kA short-time withstand current, the E6V-A is particularly suited to high-capacity switchboards and critical incoming or feeder circuits. Horizontal rear terminals facilitate connection to substantial busbar systems, while auxiliary contacts and breaker-position indication support integration with control, signalling and supervisory systems.

Typical Applications

• Main low-voltage electrical distribution boards.
• High-capacity industrial switchboards.
• High-current incoming and feeder circuits.
• Manufacturing and process plants.
• Large commercial and infrastructure power systems.
• Transformer and generator distribution installations.
• Electrical systems requiring high fault-current performance and electronic LSI protection.
